Benefits of the Cloud CPE Solution
Juniper Networks Cloud Customer Premises Equipment (CPE) solution offers an automated branch network environment, leading to cost savings over traditional branch networks, while improving network agility and reducing configuration errors. The centralized deployment offers a fast migration route through either existing equipment or a Layer 3 network interface device (NID), and is the recommended model for sites that can accommodate network services—particularly security services—in the cloud. Use of a CPE device such as a NFX Series Network Services platform or SRX Series Services Gateway in the distributed deployment supports private hosting of network services at a site and offers software defined wide area networking (SD-WAN) capabilities. Implementing a combination network in which some sites use the centralized deployment and some sites use the distributed deployment provides appropriate access for different sites.
Traditional branch networks use many dedicated network devices with proprietary software and require extensive equipment refreshes every 3-5 years to accommodate advances in technology. Both configuration of standard services for multiple sites and customization of services for specific sites are labor-intensive activities. As branch offices rarely employ experienced IT staff on site, companies must carefully plan network modifications and analyze the return on investment of changes to network services.
In contrast, the Cloud CPE solution enables a branch site to access network services based on Juniper Networks and third-party virtualized network functions (VNFs) that run on commercial off-the-shelf (COTS) servers located in a central office or on a CPE device located at the site. This approach maximizes the flexibility of the network, enabling use of standard services and policies across sites and enabling dynamic updates to existing services. Customization of network services is fast and easy, offering opportunities for new revenue and quick time to market.
Use of generic servers and CPE devices with VNFs leads to capital expenditure (CAPEX) savings compared to purchasing dedicated network devices. Set up and ongoing support of the equipment requires minimal work at the branch site: for the centralized deployment, the equipment resides in a central office, and for the distributed deployment, the CPE device uses remote activation to initialize, become operational, and obtain configuration updates. The reduced setup and maintenance requirements, in addition to automated configuration, orchestration, monitoring, and recovery of network services, result in lower operating expenses (OPEX).
